The Colibri MB-2 aircraft took off from ILAS Airfield, Taghmon, Co. Wexford for a local flight. Shortly after take-off the canopy of the aircraft opened unexpectedly. The Pilot, who was the sole occupant, managed to close the canopy but was unable to lock it shut. Whilst holding the canopy closed with one hand, the Pilot completed a circuit and approach back to ILAS Airfield. During the final approach the aircraft flared slightly too high, followed by a hard landing. The aircraft sustained damage to both main wheels, the propeller and the left wing. The Pilot reported no injuries.
